"I always believe in paying it forward and I said there’s going to be someone out there that could possibly help," Patty Williams said.

Patty Williams posted a plea on Facebook that included details about what was found in the bag.

One of the hats says Newmarket, New Hampshire on the side. The names Frank O’Harvey and Edward Johnston are both listed on envelopes, along with addresses in Haverhill, Massachusetts. The letters are signed by a soldier named Charles, and almost all of them were written in 1942, leading the Williams family to believe he served in World War II.

If they find the owner, or any of his relatives, the family said they will happily hand over the bag and the history within it.

"I need to prove to my children that in this crazy world we live in and all the violence that surrounds us that there are some good people in this world that are willing to help," Williams said in her Facebook post.
